This wearable sleeping bag isn't the first time someone's designed bedding you can stay in all day long—that honor probably goes to Selk. But it is the first sleeping bag you can wear that doesn't make you look like you're wrapped in a ridiculous puffy spacesuit.

At night, Doppleganger Outdoors' wearable sleeping bag entombs you in a cocoon of fiber filled polyester, keeping the cold out with sealable sleeves and a bag that wraps around your legs and feet. But the bottom half of the $130 sleeping bag can actually be removed in sections, turning it into a long winter coat, or a shorter jacket when you need the freedom to move around. Not only is it a more comfortable approach, but you can also roll up and compress the bottom section so it's small enough to stash in a pocket, helping keep your camping kit as minimal as possible.
